Frequently asked questions -
Credit Card (Master, VISA, Amex, Diners mainly) is surely common in Japan but not that much convenient as it is here . You need some cash.
We don’t have ATMs at every block. Very few foreign retail banks are active down there. Citi has some branches, as well as HSBC. No PNC, no… If your Bank card has Alpha plus /Cirrus (see its back), there will be a good chance that you can withdraw at local bank’s ATMs. At any case, be sure to check with your main bank where and how you can get cash before your travel .
Of course you can exchange at the airport – maybe the most stress-free way if you don’t wanna get stuck at the banks in town.
Traveller’s check is valid but you may see the difficulties in cashing them. No check is accepted in Japan regardless the issuing bank.
